Legal dispute grows over plans to replace 19th-century stained glass at Notre Dame with contemporary art, sparking heritage concerns.
Newsroom (04/05/2026 Gaudium Press) The decision to replace several 19th-century stained-glass windows at Notre Dame Cathedral in Paris has sparked a renewed heritage controversy, opening a legal battle between French authorities and preservation groups. The official authorization to remove six historic windows, publicly posted inside the cathedral between April 17 and 20, has triggered a two-month legal window for appeals.
Heritage advocacy group “Sites et Monuments” has announced its intention to challenge the decision in court, arguing that the planned intervention constitutes a modification—not a restoration—of historical elements that were left undamaged by the 2019 fire.
A Contemporary Vision for Notre Dame
The proposed project involves removing six stained-glass windows located in the south nave chapels, originally installed during the 19th-century restoration led by architect Eugène Viollet-le-Duc. These windows are to be replaced with contemporary designs by French artist Claire Tabouret, created in collaboration with the Simon Marq workshop.
With an estimated budget of four million euros, the initiative aims to leave a “21st-century mark” on the cathedral. However, critics emphasize that the targeted windows survived the 2019 blaze intact and were subsequently cleaned or restored, making their replacement controversial.
Ongoing Legal Challenges
This is not the first legal dispute surrounding the project. In November 2025, the Paris Administrative Court rejected an initial appeal from “Sites et Monuments,” which questioned whether the public body overseeing Notre Dame’s reconstruction had the authority to undertake such modifications. That ruling is currently under appeal.
The new legal action focuses specifically on the authorization to remove the stained-glass windows, intensifying scrutiny over whether the planned works comply with France’s strict heritage protection laws.
Concerns Over Protected Heritage
Opponents argue that the stained-glass windows are protected as part of a Historical Monument and that their removal would undermine the principles of conservation enshrined in French legislation. They contend that replacing well-preserved historical elements cannot be justified as restoration.
Further fueling criticism, France’s National Commission for Heritage and Architecture issued an unfavorable opinion on the project in July 2024. Despite this, the plan has continued to move forward.
Public Opposition Gains Momentum
Public resistance has also been significant. A petition titled “Let’s preserve Viollet-le-Duc’s stained-glass windows in Notre-Dame de Paris,” launched by La Tribune de l’Art and supported by “Sites et Monuments,” has gathered more than 335,000 signatures.
The association has pledged to continue its efforts even if legal appeals fail, calling for the eventual reinstatement of the original windows and the preservation of Viollet-le-Duc’s vision.
Restoration or Reinvention?
Rebuilt through global donations following the devastating 2019 fire, Notre Dame stands as both a symbol of resilience and a focal point for debates about historical authenticity. For critics, replacing intact 19th-century stained glass represents an unnecessary alteration to a key component of the cathedral’s identity.
The outcome now rests with France’s administrative courts, which must determine whether the removal aligns with the legal framework governing the protection of national heritage.
